qt terminal on Cygwin

[Tatsuro M. <tma...@ya...>]

I have tried the patch for qt-5.4.0 in the below thread

https://sourceforge.net/p/gnuplot/mailman/message/33212164/

For gnuplot

Now Qt version for cygwin is 5.9.4

However, code of corresponding part is changed to

    // create the socket
    if (-1 == (d->connectingSocket = qt_safe_socket(PF_UNIX, SOCK_STREAM, 0, O_NONBLOCK))) {
        d->errorOccurred(UnsupportedSocketOperationError,
                        QLatin1String("QLocalSocket::connectToServer"));
        return;
    }

I commented out the above


The result is

gnuplot> pl x
gnuplot> pl x
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-MATSUOKA LAB'
Could not connect to existing gnuplot_qt. Starting a new one.
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-MATSUOKA LAB'

Warning: slow font initializationgnuplot>


But the situation is the same as before modification.

Any suggestions?

I at the moment use wxt terminal on Cygwin
